The suggested tool to make your bootable USB is dd if you start from Linux, or Fedora LiveUSB Creator if you start from Windows.

I'm in trouble. I'm unable to see windows 7 while booting. So I tried to add menu entry in grub.cfg. But I'm getting an error permission denied. Kindly please help me.

Where are you getting permission denied?
Are you root?
